Summary

The goal of this study is to learn if a new pre-workout supplement can improve exercise performance in healthy adults. It will also look at how the supplement affects mood and energy levels. The main questions it aims to answer are: Does the pre-workout supplement improve endurance and strength during exercise? Does it reduce how hard exercise feels (perceived exertion)? How does it affect participants' mood and energy? Researchers will compare the pre-workout supplement to a placebo (a look-alike powder that contains no active ingredients) to see if it works. Participants will: Take the pre-workout supplement or a placebo before exercise in two separate sessions; Complete exercise tests after taking each one; Report how they feel during and after exercise, including mood, energy, and effort. By bridging gaps in existing research, this study aims to establish a robust scientific foundation for the application of this novel pre-workout supplement in enhancing exercise outcomes.
